導致織軸出現勒紗軸的原因

       由于織軸上的經紗是相互平行的,卷繞為純圓周卷繞,各卷繞平面是平行于織軸盤片平面的,當內部的經紗沿軸向卷繞密度(體積密度)不一或軟硬程度不一時,在外部經紗的強大壓力下,內部經紗卷繞松軟的地方較卷繞堅硬的地方收縮量就很大,以致形成明顯的陷落或塌陷現象,可能在塌陷部位或陷進結合部或陷進裂縫中,就形成了勒紗軸。
       一般情況能看到勒紗部位與兩側紗面高度不一,織軸卷繞直徑越大,外部經紗對內部經紗的壓力越大,越易產生勒紗疵軸。此外,經紗卷繞密度過小,過于松軟或沿軸向局部經紗回潮率過大而使卷繞密度不一,易形成勒紗軸。
       減少勒紗軸應從減少造成織軸卷繞密度差異或過于松軟有因素著手。
